Version 4.001


  • Define Bolt Properties from the following types: Mechanically Anchored, Grouted Dowel, Cable Bolt, Split Set, Swellex, and Simple Bolt Force
  • Option to use bolt Shear Strength instead when the bolt is in the right deformation mode
  • Option to apply Bolt Orientation Efficiency factor calculated from the Cosine Tension/Shear or Linear Tension/Shear method
  • Bolt Model (Active/Passive bolts) is now associated with Bolt Property instead of each individual bolt


  • Apply Ponded Water Pressure to the Slope and/or Upper Face by specifying the depth of ponded water
  • Define Slope Face Type from the following types: Pervious and Impervious
  • Model Plane Water in conjunction with Ponded Water
